heiio everyone; i hav some queries regarding i2c communication
1.what is the range an i2c communication travel without affecting the data
2.how many devices can we connect on i2c-i have read 127 addresses, can u explain me this?
3. what is the difference between i2c,rs232 and rs484
thank u all
i2c will function as long as the distance is less than 12 feet male cow manure! IIC will function as long as the drive vs the line capacitance is OK. That can be exceeded anywhere between a few inches and many feet.
If you need go farther NXP has "IIC amplifiers" that can drive more capacitance.

alright, alright, I was just giving an example for a total bus capacitance of 400 p/F...sorry, please don't bite my head off! but it is a good thing you corrected me and alerted the OP!
I was just giving an example for a total bus capacitance of 400 p/F the "total bus capacitance" you can handle, again depends on the pullup resistors.
no "head biting" just facts.
everything re IIC depends on.
Yes, if you use the minimum pullup resistors (can your uC handle that??) you can handle the maximum capacitance.
